PEGGING-MACHINE.

Specification of Letters Patent.

Patented Apr. 4, 1911.

Application filed March 4, 1898. Serial No. 672,507.

To all whom it may concern: I

Be it known that I, BENJAMIN F. MAYO, of Salem, county. of Essex, State of Massachusetts, have invented an Improvement in Pegging-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters 011 the drawings representing like parts.

This invention relates to pegging machines and particularly to that type of machines which employ a peg ribbon.

It is now the usual practice in pegging shoes to employ a machine which drives through the outer sole of the shoe a peg of a length longer than the thickness of the soles or other parts to be united so that it is necessary to cut off the driven pegs flush with either or both the inner and outer soles.

The pr ncipal ob]ect of the present invention 1s to produce a pegging machine, es-

' pecially adapted to operate upon shoes but aspect,

equally useful for other purposes, in which the length of each peg formed will correspond with the stock into which it is to be driven so that each peg when driven will be of a length suitable for the stock whatever its thickness and there will be no occasion for cutting off the end of the pegs after they have been driven.

Accordingly the present invention, in one comprises the combination with means for supporting a peg ribbon, of means for shortening the peg or determining its length, and means to change automatically the relative position of the ribbon support and the peg shortening means according to variations in the thickness of the stock being pegged, together with such other cooperating elements as are necessary to a practical, organized pegging machine, including, for example, a peg driver and an awl, which preferably will also be utilized for feeding the stock.

More specifically the invention comprises means for forming pegs of a length varying according to the position of a vertically movable horn or other support for the stock which is arranged to cooperate with a vertically stationary foot plate or other fixed abutment for calipering or measuring the stock, and which is preferably actuated automatically to release the pressure upon the stock while it is being fed.

In addition to the peg shortening means, just referred to, the machine is preferably provided with means which cuts into the peg ribbon transversely and thus cotiperates with the peg shortening means to detach directly from the peg ribbon a shortened peg. Broadly considered, the invention, in this aspect, comprises means to detach directly from a peg ribbon pegs of varying length and means controlled by the thickness of the stock being pegged for determining the length of the pegs.

\Vhile some of the features ofthis invention are not limited to a construction in which each peg at the time that it is detached from the peg ribbon is of the proper length for the particular thickness of stock into which it is to be driven, yet this is an important feature of the invention and this manner of obtaining pegs of the proper length is considered preferable to that in which a peg having a length equal to the full width of the peg ribbon is first formed and then is subsequently shortened to the desired length for driving. For instance, where, as herein set forth, the peg is shortened while still attached to the ribbon it may easily be held in proper position with relation to the shortening means and may also be well sustained against the thrust of said means so that the peg will not be broken during the shortening operation but will be shaped accurately.

The peg forming means herein described and shown includes two cutting edges, one of which acts transversely of the peg ribbon to detach a peg and the other of which acts longitudinally of the ribbon to determine the length of the peg. These two edges may be formed on separate parts or elements of the machine, but it is convenient to employ for these purposes two edges at right angles to each other upon a single bar or part. The edge which cuts into the peg ribbon transversely will, in such case, have a width substantially equal to the width of the ribbon, this edge acting alone to form a peg when the peg is to be of a length equal to the full width of the ribbon. If, however, the peg is to be of a length less than the width of the ribbon, then the other edge which acts to shorten the peg will cut the peg ribbon longitudinally between the two edgesof the ribbon, thus defining the upper end of the peg and consequently its length.

In order to make the leading end of the peg ribbon straight when a peg shorter than the width of the ribbon is detached, I have provided means to remove from the ribbon the surplus material not needed in the peg. While this surplus material may be removed from the ribbon either before or after the peg about to be driven is detached from the ribbon, yet, as herein shown, the peg is first detached and then the surplus or stub left at the end of the ribbon is removed by the surplus remover so that the leading end of the peg ribbon will present a plane surface substantially at right angles to the edges of the ribbon. In the preferred embodiment of the invention, the peg forming means and the surplus remover are moved back and forth substantially at right angles to the peg ribbon support and to the ribbon sustained thereby so that the peg is severed from the ribbon and then the material not needed for the peg is removed by the surplus remover during the time that the peg forming means is carrying the peg into position for driving.

A feature of the machine as herein illustrated is that the successive pegs, which may be of varying length, are each driven immediately after formation and before another peg is formed. Another feature of the machine is that the peg forming means is actuated through connections from the stock feeding head so that no additional cam, or other part on the main shaft, is required to actuate the said means, the peg being formed during the movement of the head.

Mechanism will usually be provided for feeding the peg ribbon forwardly to bring it into proper relation to the peg forming means. Preferably those parts of the feeding mechanism which engage the ribbon, as well as a holder for a coil of the ribbon, are mounted to move vertically with the peg ribbon support.

Other features of my invention will be hereinafter more fully described and pointed out in the claims at the end of this specification.

Referring to the drawings,--Figure 1 is a left side elevation of the upper part of a pegging machine embodying my invention in the preferred form; Fig; 2 shows the lower part of said machine, Figs. 1 and 2 together showing the entire machine; Fig. 3 is a front elevation of the part of the machine shown in Fig. 1; Figs. 4L and 5 are details showing parts of the peg ribbon support or guide and part of the feeding mechanism for the said ribbon; Figs. 6 and 7 are views upon a larger scale in front elevation and plan respectively of the nose and part of the peg ribbon support; Fig. 8 is a section on the line wm, Fig. 7; Fig. 9 is a section on the line ww, Fig. 6; Fig. 10 is a section on the line g 3 Fig. 8; Fig. 11 shows in front elevation, partly broken away, another form of the devices shown in Fig. 8; Fig. 12 is a section on the line w m Fig. 11, and Fig. 13 shows the end of a piece of peg ribbon and indicates the manner in which a peg is detached therefrom.

I have chosen for the sake of illustrating my invention in a practical working machine to show it as applied to a machine of the type represented in Letters Patent of the United States No. 490,624, dated January 24:, 1893. Therefore many of the parts illustrated in the drawings are substantially like those in the said prior machine. Thus, the movable head B carrying a driver bar a provided with a driver if, and containing an awl bar 7 provided with an awl f; the link a resting on the upper end of the driver bar, the arm 6 the spring a the main shaft C having at its front end a disk 6 having a driver lifting projection e and a cam face 9 said projection e acting on a projection from the block 6 connected with the driver bar to lift the said driver bar; the camD fast on the main shaft C the arm f actuated by a groove at one side of said cam, and rocking the shaft f having an attached arm f provided with segmental teeth engaging teeth of the awl bar; the arm D also actuated by a groove in the cam D, said arm being fast on a shaft D provided at its front end with a feed arm De, grooved to receive a divided block D, the stud D carrying it and entering the groove between the head B and the finger B connected therewith to rock the movable head B and enable the awl in the stock or work to feed the stock over the stock support or horn B; the wedge C carried by. the rod 0*, the lever C pivoted upon a stud in the head A and having connected to it a red C which, through suitable connections, depresses the stock support at the proper times; the brake B, the brake wheel C the cam B connected therewith; the nose E in which both the driver and the awl work, the driver working in a driver passage in the said nose; and the foot plate I), are or may be all substantially as shown in the patent above mentioned, wherein the same letters are used to designate like parts. I will also state that the stock support B mounted on a shaft 5 adapted to move vertically in a bearing a rising from the column A which supports the head of frame A, the rod Z2 connected to the lower end of the stock support and attached to a lever C", said rod being surrounded by a spring I)", the rod (Z connected with one end of the lever C and having at its upper end a ratchet plate a adapted to be engaged by a pawl 61, pivoted in a carrier (Z working in guideways (Z and having attached to it the rod 0 and the rod C heroinbefore referred to, are or may be substantially as represented in Letters Patent of the United States No. 383,455, dated May 29, 1888, so that said parts need not be herein more specifically described. It will be understood therefore that the awl is actuated to make a hole in the stock and to feed the same and that the driver bar and driver are reciprocated to cause the driver to descend atthe proper time in the driver passage of the nose E, and that the stock support is automatically lowered after driving each peg thereby to release the stock in order that the awl, in the lateral movement of the head B, may feed the stock support then rises to clamp the stock whatever its thickness may be, the said stock support occupyingavarying position according to variations in the thickness of stock being pegged so that the stock support and foot plate 6* serve to caliper the stock which passes between them. According to the present invention I make use of this calipering means to produce the change, heretofore referred to, in the relative positions of the peg ribbon support and the peg shortening means, as will be hereinafter described in detail.

I prefer to use for the peg ribbon a strip of peg wood F rectangular in cross section so that the pegs will present a smooth surface not only at the inner side of the inner sole, but at the outer face of the outer sole, it being understood that, in shortening the pegs, the cut is made at right angles to the length of the peg.

Instead of the lever employed in said Patent No. 490,624 for actuating the separator for taking off from the raceway the headed nails to be driven, I have substituted in the machine an oscillating lever h which forms a part of mechanism for feeding the peg ribbon. The lever is secured to a stud 71, extended from the movable head B and at its upper end the lever is provided with a roller or other stud it which is constantly pressed against the cam face g by the spring 9. The lower end of this lever la is provided with ears h, shown best in Figs. 1 and 5, provided with adjustable stops, represented as screws h, said stops in the oscillation of said lever meeting the free vertically widened end it" of a feeding pawl or like device the point it of which passes through a slot h in one side of the peg ribbon support or guideway F and engages one side of the peg ribbon F. A stud it on the pawl is free to slide longitudinally of the ribbon support in a slot h of a block stock and that the horn or 11, fixed to the support, a spring h serving normally to keep the point of the pawl against the side of the ribbon. Fig. 5 represents these parts in the positions they occupy during the feeding of the ribbon towardthe nose E. One of the stops it of lever 71/ as shown, acts upon the free end it" of the pawl and forces the point [1, firmly into engagement with the ribbon so that, as the lever 71 is moved to the right, the stud h slides in the slot 71. and the ribbon is moved forward positively. In the reverse movement of the lever h, the other stop it, acting on the end It, will remove the point of the pawl from its engagement with the ribbon and the pawl will slide backwardly over the ribbon without moving it. During this backward movement, a detaining device shown as a pawl or detent h pivoted at I and acted upon by a spring h prevents the peg ribbon from moving backwardly away from the nose.

The driver guide E shown in Figs. 8 and 11, is like that in Patent No. 490,62 l, above mentioned, and it has the nose E connected to it by a screw 8. The driver passage 12 in said driver guide is open at one side, as best represented in Fig. 8. The formed peg is pushed through this open side into the space 10 in said passage 12 and the driver drives it therefrom into the stock. This passage 12 may be tapered slightly, as shown in Fig. 8, being smallest at its lower or delivery end. When the peg is driven, it is compressed as it is forced through this passage and it enters the stock in a compressed condition.

The driver guide E has fitted to it, as shown in Figs. 7 and 12, a block E which has a lug 13 embracing a portion of the driver guide. This block E, which is secured to movable head B, is grooved to sup port and guide the peg forming means and the surplus remover, about to be more fully described.

As shown particularly in Fig. 8, the peg forming means comprises two cooperating cutting edges 15*, 15*". The edge 15, which severs the peg from the ribbon, is vertical and cooperates with a vertical edge of the wall 80 of a throat 36 which extends through one end of the block E and opens into the space 10. The edge 15"", which shortens the peg, occupies a position at right angles to the edge 15* and cooperates with the edge of the upper wall of the throat 36. These edges 15*, 15 are, as herein represented, formed upon a single blade or bar 15. The acting edge 14? of the blade 14: which constitutes the surplus remover is preferably located hehind the edges 15*, 15 ofthe peg forming device and the two blades 11, 15 are adjustably connected by means of a bolt 16 passing through a slot 17 in blade let. The surplus remover meets that portion of the are detached at the proper times.

peg ribbon-which contacts with the wall of block E above the throat 36 and removes the portion of the ribbon not needed for the peg just formed-by the peg-forming means.

slot 30 of the block E that the pegforming means will punch out and detach a shortened-pegdirectly therefrom, the head of the peg beingvat a distance from the upper edge of theribbon'or strip equal-to the distance between said edge and thesurface 35 0f the throat 36.

The peg forming means and the surplus remover are kept properly seated in the groove of the blockE by means of a cap 39, shown'as partially broken away in Fig. 7 through which are inserted suitable screws 40.

For actuating. the blades 14 and 15, I provide a swinging arm 20 having, at itslower bifurcated end, a pin 19 which passes through a slot 18 in blade 15. This arm 20, which is'pivoted at 21 upon frame A, is provided wit-h a stud 22, shown in Figs. 1 and 3, which is arranged'to be engaged by adjustablescrews 23, 24c in cars of a' link 25 which is slotted to receive the stud. This link is pivotally connected at 26 to the movable head B, so that in its stock feeding movement the head swings the arm 20 carrying forward the peg forming means and the surplus remover but at a greater speed than the peg ribbon, which also moves laterally with the head, so thata. shortened peg and the surplus or stud end of the ribbon .The throw of the arm 20 may be regulated by adjusting screws 23,. 24: thus changing the amount of lost motion between arm 20 and link25. The screw 23 is so adjusted that at the end of the swinging movement of headv B to the right, as shownin Fig. 3, the end of blade 15 will have carried the'formed peg into the portion 10 of the driver passage andwill close the open side of the passage during the driving of the peg. By adjusting bolt 16 in slot 17, the edge 148 of blade 14 is caused to sever the surplus end from the peg ribbon just as the blade 15 puts the peg into the space 10. The blades let and 15 will remain in these positions after the head B commences. to move toward the left and until the end of screw 24 engages stud 22 when the lost motion between arm 20 and link 25 will have been taken up. The ad' justments just described also provide means for compensating for the change in position of the edges of the blades due to grinding or sharpening;

The roll or coil of peg ribbon-F is supported upon a circular table 1" having pins 1 rising-fromit between which the coil lies.

This table has a downwardly projecting central pin which enters loosely .a hole in an arm r extended from the head or other stationary part of the frame so that as the peg. ribbon support F which is fixed to the table, is movedvertically. the table will, i move with it, a sufficient amount of play being provided between pin 1' andits hole.

In-order that thepeg ribbon support F" may be moved vertically to vary the length 0111116 peg formed, the block E is provided, as shown in F igs.-7 and 10, with a groove to receive and-guide a projecting rib m upon a slide piece F at the. forward end ofthe.

ribbon support. Parts F and F may be secured together in any suitable manner, as

by meansof an angle iron F and suitable 1.

screws. The slide piece F receives a stud or other screw F which .is embracedby one end of a link m the other end of which is partly cylindrical in form and .is seated in a correspondingly shaped groove in the front end of a lever m pivoted at m on a stand at erected on a-fixedpart of the head A. \Vhen the block E and the end F of the peg ribbon support move laterally with mental in depressing the stock support, so

that whenever the rod cl is lifted bylever C and connected parts to depress the'stock support I the rear end of the lever m will also be lifted to depress the peg ribbon support'and its end F in unison with the stock portion F of theribbon support on-which rests the lower edge of the ribbon will be raised and lowered in the slot: 30 in the block E It will usually'be desirable to provide means whereby movements of the stock sup port greater than those ordinarily. occurring while the machine is in continuous operation, and particularly the extra depression of the stock support to permit removal of a shoe, will not cause equal move ments of theribbon support. This feature. is not claimed herein, however, being fully support and it will be understood that that described and claimed in my Patent No.

834,923, granted November 6, 1906. Whether or not such means is provided, the

. peg ribbon, while the machine is running normally, will be raised and lowered with relation to the throat 36 in block E and to the edge 15 which shortens the peg so that the length of peg severed from the ribbon a and driven is varied automatically according to the thickness of the stock. For examner of the edge 15 of blade 15.

ple if the length of the peg is to be equal to the full width of the peg ribbon, then the lower edge of the ribbon will stand substantially at the same height as the bottom of the throat 36 and in line with the lower cor- If, however, the peg next to be driven ought to be shorter than the width of the peg ribbon because the thickness of the stock between the foot plate b and the top of the stock support 13*" is of less thickness than the width of the peg ribbon, the peg ribbon support, under the control of the stock support will occupy. some such position as that shown in Figs. 8 and 9. Then, as the movement of head B toward the left (Fig. 3) to I feed the stock has been completed, the stock support will have adapted itself automatically to the thickness of the stock and will clamp the stock firmly between the stock support and the foot plate. Now, the awl being out of the stock, the head B is moved to the right to put the driver passage 12 immediately above the hole just made in the stock by the awl. During this movement, the link moves the arm 20 as already eX- plained and causes the peg forming means and the surplus remover to operate. The peg forming means first makes the shortening cut longitudinally of the peg ribbon and at the same time the transverse cut for forming the last side of the peg and then it pushes the peg at right angles to the line i of feed of the peg ribbon into the space 10 drive the peg.

of the driver passage and closes one side of the passage while the driver descends to The surplus remover meets the peg ribbon just before the peg forming means reaches its extreme forward position and acts upon the peg ribbon, which is sustained upon its opposite side by the block E above and at one side of the throat 36, to detach the stub at the end of the ribbon left after the cutting out of the shortened peg. In Fig. 13, which shows a piece of the end of a peg ribbon, n represents in full lines a shortened peg such as would be punched by the peg forming means from the end of the ribbon, while n represents the stud or surplus not needed for that peg which is to be cut away subsequently upon the line a by the surplus remover, leaving the leading end of the peg ribbon again straight and bon in the notch 79 is cut out from the end of the ribbon and carried into line with the driver passage so that the driver, as it descends, meets the peg in the notch 79 and drives it into the stock. In this form of construction, the length of peg is automatically determined and the surplus is removed as in the first described construction.
